Alice wishes to tell Bob about the animal she saw at the zoo Alice and Bob share the key stream 1101 1001 0000 1010 1110 1101 Alice creates a 3-character ASCII message, encodes it, and sends it to Bob. This is the ciphertext: 1001 1111 0100 0101 1011 0101 Bob deciphers the message. What animal did Alice see at the zoo?
